Been having a small coolant leak and seems one of the freeze plugs is weeping. Is it possible to install new if there is a decent amount of room to work?

It is possible if you can get a socket (about 1/4" smaller diameter than the plug) in there and be able to hit it with a hammer. You may have to remove a header and crossover, or the starter, but it is possible. If not, worst case scenario for semi-temporary uses they used to sell a rubber plug that had a wing nut on the end with a bolt run through the middle. Tighten the nut and the rubber expands, sealing the hole. Again, wouldn't run it like this for long, but if you are in a bind could work. Or, if you are like me, convince the wife you MUST pull the motor now, and since you are there you should upgrade the heads, cam, turbo, etc, etc. I usually get myself in trouble that way. :biggrin:
They make freeze plug installation tools that most professional mechanics have. They have all kinds of adaptors and a angle driver to reach most plugs. Here is what they look like:
